Follow-up to the review hardening: the replay ran on EVERY agent start with a 5-minute window, first run included. On a first run there is no gap to recover — no earlier agent process existed — and a 62407 already sitting in the Shell-Core log belongs to a phase transition this agent was never meant to observe. Replaying it pushes an EspExiting into the reducer that the pre-fix agent never saw, i.e. a happy-path behaviour change for no gain. ResolveEspExitBackfillLookbackMinutes now keys the window to the previous exit type: first_run (or unknown) disables the replay entirely, clean/hard_kill/ exception_crash keep the 5-minute default because the process is back within seconds, and reboot_kill widens to "since LastBootUtc" because that gap spans the forced restart until the post-reboot logon. The result is still clamped to BackfillLookbackMaxMinutes, so policy and backstop together cannot build an unbounded event-log query. With this the happy path is byte-identical to pre-fix behaviour: on a first run nothing replays, no edge is remembered, and the deferred re-check returns on a volatile bool read. No other backfill is affected — the Hello, MDM-reboot, Windows-Update and ModernDeployment trackers each own a private backfill invoked from their own Start(), none of which this change touches. 13 policy tests including clock skew across the reboot, a missing boot timestamp and the clamp backstop.
